OT Security / OT assessment & Cyber Vision
OT assessment.Understand first, then protect deliberately.
A production network cannot be assessed responsibly from a device list alone. We map assets, communication relationships and operational boundaries, optionally using Cisco Cyber Vision, and turn visibility into prioritised next steps.
Scope of service
What you receive.
This service fits incomplete inventories, segmentation preparation, audits that require dependable evidence, and environments introducing or improving Cyber Vision. The starting point is deliberately observational. Active queries or production changes only take place after technical assessment, approval and an agreed window.
A traceable OT inventory
Devices, roles, networks, peers and available context are brought together. Unknown or ambiguous components remain marked as such instead of being disguised with assumed product names.
Communications, not just addresses
Recurring flows, transitions between zones and unusual paths become visible. This helps distinguish operationally required relationships from access that merely accumulated over time.
Prioritised risks
Technical findings are evaluated with criticality, reachability, operational consequence and existing compensating controls. A high product score alone does not decide the sequence for your plant.
An implementable next step
You receive findings, assumptions, open questions and prioritised measures. Potential follow-on work such as segmentation, remote access or operational integration is clearly separated rather than implied as part of the assessment.
The delivery path
Three controlled steps.
- 01
Define scope and safety
Agree plant areas, contacts, operating periods, sensor paths, approvals and exclusions. Protecting production determines the collection method.
- 02
Observe and interpret
Combine available telemetry, configuration and operational knowledge. Validate findings with plant owners while retaining visible knowledge gaps.
- 03
Prioritise risks and action
Turn observations into decisions, state prerequisites and ownership, and select a realistic first implementation step.
What we agree before starting
A time-limited assessment is not continuous monitoring or certification. Visibility depends on sensor placement, protocols and the operating states present during observation. Active discovery, plant access, remediation, round-the-clock monitoring and regulatory legal advice are included only when explicitly agreed.
Good to know
Your questions. Clear answers.
Does Cisco Cyber Vision need to be installed already?
No. We can assess existing data, design an appropriate collection approach or begin with other available sources. Whether Cyber Vision fits the target architecture depends on visibility, integration and the operating model.
Does the assessment change production systems?
Our standard starting point is passive. Every active query or technical change is assessed separately and needs approval from the plant owners. Where even passive collection could have an impact, the sensor path is reviewed first.
Will we receive a complete asset list?
You receive the observed and validated state within the agreed scope, including its limitations. Devices that do not communicate during the period or are invisible to the sensor path may be absent; that gap is documented explicitly.
Let’s discuss your requirements
A few details are enough to begin.
You do not need a finished design. We establish the need, boundaries and a dependable next step.
